Remove need for Rc<RefCell<_>> usage

This adds a trait OnResize and a separate method handle_resize to the
display. Instead of having a callback to receive resize events, a list
of &mut OnResize are passed to this new method. Doing this allowed the
only RefCell usage in the codebase to be removed :).
